President Trump told Fox News he is “surprised” Deputy Attorney General Rod Rosenstein won’t testify Thursday on Capitol Hill about reports the Justice Department official suggested secretly wearing a wire to record the president, considering their conversation on Air Force One earlier this week.

The president said they discussed Rosenstein’s reported comments – including that Rosenstein once suggested invoking the 25th Amendment to remove him from office last year.

The New York Times first reported the details of the alleged discussions between Rosenstein and senior FBI officials in May 2017, one day before Rosenstein appointed Special Counsel Robert Mueller to oversee the Russia investigation.

Trump’s lawyer, Rudy Giuliani, on Thursday confirmed to Fox News that Rosenstein told Trump his comments on wiretapping were “sarcastic.” Further, he said Trump did not believe Rosenstein considered invoking the 25th Amendment to oust him.

But as reported by Fox News, former FBI general counsel James A. Baker told congressional investigators during a closed-door deposition last week that two senior FBI officials at the time told him they believed Rosenstein was “serious.”
